Set up CI

[Sudha247]

To prevent build failures like the ones mentioned in #47, a CI will be useful. We can use GitHub actions and setup-ocaml for setting up the CI. Here's an example - https://github.com/ocaml-multicore/domainslib/blob/main/.github/workflows/main.yml.

Great job @TitilayoAdeyemi! :)
Thank you so much for your amazing contribution. Through this, I got to learn more about continuous integration.

I've done a little refactore of the CI in my present PRs so all the checks are passed now with no issues.

@nangahamandine I noticed the CI failures due to dependencies on windows, too. Can you submit a separate PR for fixing it so we can review and merge it quickly, please?

Okay, sure. I'll do that now.

Please review.
